BAUMAN, OF CHICAGO, ILLINOIS, ASSIG-NOR TO UNIVERSAL FORM CLAMP CO OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS BAR SUPPORT SPACER Application filed February 17, 1930. Serial No. 429,116.

The main objects of this invention are to provide an improved bar support and spacer for use in reinforcing systems of concrete con-' struction work; and to provide a bar support and spacer which may be fabricated out of a single piece of wire.

-An illustrated embodiment of this invention is shown in the accompanying drawings, wherein:

Figure 1 is a perspective of an improved bar support and spacer.

Fig. 2 is a fragmentary top planshowing two reinforcing bars supported on two of the improved devices, part of the mold solht being shown in dotted outline.

Fig. 3 is a transverse vertical section, taken on the line 33 of Fig. 2, the dotted lines showing the reinforcing bars preparatory to being pressed downwardly into their seats.

Fig. 4 is an enlarged end elevation of one of the devices, showing also part of a reinforcing bar.

The common types of bar support and spacer heretofore in use generally included a plurality of supporting members secured to spacing strips which spaced them uniformly from one another. In the manufacture'of those devices, the supporting members and spacing strips were separately fabricated and then assembled in units. Each unit consisted of separately formed parts of different shapes which required several different dies It was also necessary for the manufacturer to carry in stock a large supply of each part p of the units.

possesses the necessary rigidity and which may be bent to the desired shape.

The reinforcing system involves the use of a plurality of reinforcing bars 1, disposed horizontally above a falseworlr, such as a joist soflit 2, and supported in substantially parallel spaced relation by a plurality of the improved 'supportsfand spacers.

Each of the improved devices comprises a Wire which is bent to form two or more substantially-U-shaped supporting saddles 3 for receiving the'bars 1. The side arms of the saddles are crimped inwardly to define restricted throats a of slightly less width than the reinforcing bars, so that it is nesessary to press the bars through the throats when placing them in the saddles; The side arms of the saddles are yieldable so as to permit expansion of the throats when the bars are inserted. 1

The inner arms of two adjacent saddles are connected by a horizontal portion 5, which serves as a spacing rod for spacing the reinforcing bars the required distance from each other. The outer side arms of the saddles are bent outwardly to provide spacers 6 Whichare adapted to engage the side walls of the mold, not shown.

' In the construction shown, the base of each saddle is bent at its central portion to provide a pair of downwardly diverging legs 7 and a horizontalfoot 8 arranged to form a substantially triangular support which is located in a plane disposed at substantially right angles to the plane of the saddles 3.

In operation, the improved devices are placed on the falsework at the desired intervals and the reinforcing bars are then pressed downwardly into their seats. The bar supports and spacers embodying these improvements are exceedingly simple in construction and operation, comparatively inexpensive to manufacture and very rigid when setup.

I claim:

A bar support and spacer comprising a single piece of Wire bent to form a pair of substantially U-shaped saddles disposed in a single plane and spaced from each other, the outer arms of said saddles being bent outwardly, the inner arms of said saddles being bent inwardly and connected together, the base parts of said saddles being bent to form depending triangular supports intersecting the plane of said saddles, said saddles having restricted throats.
